Cartridge Heater

The cartridge heater is of pipe form, from one end of which lead wires are drawn out. Effective heating is obtained simply by inserting it into the substance to be heated.

Points to be observe when using cartridge heaters

for cartridge heaters with surface loads up to 20W/cm the receiving hole must be drilled with small tolerance and a sliding fit is necessary.

the drilled recieving bores for cartridge heaters must be cylindrical, crossing bores and shringkages cause a localisation of heat and shorgen the useful life of the heating elements.

the end of the cartridge heater with the connection lead should be protected against liquid and pasty media (lubricants, oil, synthetic materials, etc) because otherwise leakage currents and, possibly flashover could occur at the outlet connection terminals.

the connection leads should be protected against mechanical vibrations close to the outlet of the cartridge heater.

if possible, control of the operating temperature shoud be realised by means of continuous regulators, by controllers with pulse widht modulation or electronic power control device. a control system with long timelag often causes thermal overload of the heating elements. for this reason also the temperature sensor must be fitted in close proximity to the cartridge heater about 10mm apart.

when using several cartridge heaters the distance between two consecutive cartridge shoudl be at least equal to the cartridge diameter.

if heating elements are to be stored for long periods they should be housed in absolutely dry roms or enclosed in plastic bags which are hermetialy sealed.

TEMPERATURE SENSOR

Thermocouple is made by joining two dissimilar metal conductors together to form a closed circuit. when one end is maintained at constant temperature and the other end is exposed, thermal electromotive force is generated in the circuit.

Thermocouple is installed directly int he process medium, which can be corroseve and at high temperature.

A variety of thermocouple wire types is available to cover the range of temperature from -184 to 2330C.

Thermocouple wires are generally selected to provide as linear as possible a temperature-emf relation.
